#
# This script is run from custom_decode, and will remove the last
# entry from the log, sleep for two minutes, then remove the pin
# enable flag.  This ensures a command activated by pin code is only
# available for 2 mins after receiving the activate command.
#
# After the 2 min timeout, if the pin flag still exists, remove it.
# ** Your pin-activated script should remove the pin flag itself **
# As the flag is in RAM-Disk, PC reset will clear it!!
#
# Unlog (?) added to remove the pin number from the system log file.
# If this is not done, someone hearing the pin activate tone can
# recall the last loglines and discover the pin code.

# V1.0 02/02/09 - VK8SJ - Original version
# v1.1 01/01/10 - VK8SJ - added unlog command
# v2.0 12/04/21 - VK2YLD - Mod for Debian
